DRIER.

Application filed November 27, 1922. Serial No. 603,393.

This invention relates to improvements in driers and heaters, and especially to comparatively smallhousehold driers intended for use in drying laundry, althou h, of course, it might be made in sizes app icable to many purposes. One object is to rovide a drier in which the danger of score ing or burning the garments is reduced to a minimum. Another object is to provide a drier in which the su ports forthe garments are cool. Another object is to provide a drier in which the walls of the drier are heated only indirectly and are therefore revented from beingv overheated. Other 0 jects will ap- 1plear from time to time throughout the specication and claims. 1 My invention is illustrated more or less diagramatically in the accompanying drawings, wherein- Figure 1 is a front elevation of the drier with tion;

Figure 2 is an enlarged front elevation of parts broken away and parts in seca portion of the heating unit with parts in section and parts broken away; Figure 3 1s a vertical cross section taken on line 3-3 of Figure 2; 4 Figure 4 is a vertical cross section on line 4-4 of Figure 1;

Figure 5 is a vertical cross section on line 5-5 of Figure 1;

Figure 6 is a vertical cross section on an enlarged scale on line 6'-6 of. Figure 5 showing the rod attaching means.

Figure 7 is a view similar to Figure 6' showing the rod removed from itsposition and the. attaching means loosened.

Like parts are designated by like characters throughout.

A is the front vided with any suitable door frames A, A

on which are supported door members, each 'comprisin a front portion A and a rear wall A, so t at the doors are of double thickness and provided with an air slphace between their front and rear faces. e doors are provided with opposed closing surfaces A and A.

A hook member B on the upper side of the door frame is adapted to be engagedby a rod B, pivoted'at B on one of the door members and loosely confined by the strap The back of the drier ma be formed by a sin le sheet of metal 0. e sides are prefera ly double. The outer elements (P, Q

1 moved p engage the slots wall of the drier. It is pro- I! serve as walls of flues and the inner perforated elements C, C respectively allow ac? cess of alr to the interior of the drier and escape therefrom. The member C is formed ing the closure of the opening by holding.

the garments out of sea mg contact therewith. Through the members G, C there are a plurality of inlets C. v

The members O, C are further provided with a plurality of transverse hollow tubes B. These tubes may be in communication with the interior of the double end walls as shown at D D or they may extend clear through both walls and communicate with the outer air'as at D, D". In either form cooling air is circulated through the tubes," and thus they do not become hot enough to scorch or in ure anything which is placed upon them.

The tubes D are slotted at one end as at "D and they are slipped into perforations in the member 0. The slot is brought into close proximity with the inner edge of the member C and the locking bar D which is adjustably held to the member C by means of the locking bolts D and the slots D in which they lie, the lockin bar D being as shown in F1 re 6 andthe bolts being ti tened.

en it IS dBSiIGd to release the tu es, the

nuts are loosened and the locking bar is moved down as shown in Figure 7, and the tubes may then be withdrawn.

A cent the bottom. of the drier are a plum 'ty of stra members E which extend clear across the rier and upon which a wire netting E is supported. This netting E serves'to hold the articles within the drier away from the heatin elementand to prevent any scorching.

In the'bottom of the drier and. out of contact with its sidewalls is located a tunnelmade up of'a hood member This member is lined on the inside of itstop with a heat resisting lining F. It extends from end to end of the drier and communicates with-the double end walls by means of perforations F, F at each end. Extending into the inside of this tunnel is a burner G which may be of any suitable form, the details of which form no part of the present invention. Al though a gas burner is here shown as the heating element, any other suitable heating element might be used. The burner G' is supported upon a plurality of members G in the bottom of the tunnel. It is connected from the outside with a gas connection G and is controlled by means of a valve G The burner extends in preferably at right anglesto the longitudinal axis of the tunnel.

The wall of the tunnel is perforated with a generally pear-shaped hole H. The hole permits the insertion of the burner and eaves a sufiicient amount of additional space so that a match or other lighting means may be inserted through the hole over the pipe. In the wall of the tunnel is a perforation covered by mica member H Covering the lar or part of the burner is an insulating an ventilatin cover I. It extends laterally to form t e hoods I I on either side of the tunnel. Beneath the hood in the wall of the member F are a plurality of openings I I by means of which air is drawn from the interior of the drier into the heating tunnel.

At either end of the drier on the inside, is

I a collar J provided with a flange J which is attached to the' inside wall of the drier. The member F is placed in position over the collar J, and thus it is removably held in position within the drier.

K is a hand hole in the outer wall of the casing provided with a movable cover K. The hand holeis provided in order that the hand of the operator may be inserted to light the burner.

I claim 1. A drier comprisin a casing, means for heating the drier, sai means comprising a heating element surrounded by said drier and separated from the interior thereof, and means for introducing relatively cool air from outside the drier to. said heating element and for removing heated air from said heating element without permitting it to circulate throu h the interior of said drier, and means or'introducing air from the interior of said drier to said heating element.

2. A drier comprisin a casing having a plurality of double wal s, a heating element within said drier, an enclosure therefor in free communication with the interior of two of said walls, and including means forpreventing the egress of air from said heating element into said drier.

3. A drier comprising a casing having a plurality of double walls, one of said walls open adjacent its bottom to the outside and 4. A drier comprising a casing, means for.

supporting articles to be dried 'therein, said means including a plurality of tubes arranged in. a plane inclined downwardly from the front to the rear of the casing,

5. A drier comprisin a casing provided with a plurality of dou le walls, means for introducing air to one of said walls and for withdrawing it from the other, and a plurality of members for supporting articles within said drier to be dried, said members com rising tubes mounted upon the interior of t e drier in communication with said double walls whereby the circulation of air throu b said tubes is permitted.
